Routing between different subnets.

I have a little stupid question, but i'm really stucked.
We have two pfsense in different location.
In first location we have LAN net 10.200.1.0/24 with gateway 10.200.1.1.
In second location we have LAN net 10.200.40.0/24 with gateway 10.200.40.3.
All time we used OpenVPN static connect and all worked fine, but recently we got dedicated canal between two location.
I'm try to setting routing, like this:
Static route to 10.200.40.0/24 through GW 10.200.1.1.
Static route to 10.200.1.0/24 through GW 10.200.40.3.
Okay, it work, but... not good.
We have a traceroute like this:
From 10.200.1.13 => 10.200.1.1 => 10.200.40.51- looks good, but the network was unstable - especially with TCP-connections.
And iperf(for speed test) show like this:
[ ID] Interval > Transfer Bandwidth [ 4] 0.00-1.00 sec 256 KBytes 2.09 > Mbits/sec [ 4] 1.00-2.00 sec 0.00 Bytes 0.00 bits/sec [ 4] 2.00-3.00 sec 0.00 Bytes 0.00 bits/sec [ 4] 3.00-4.00 sec 0.00 Bytes 0.00 bits/sec etc.
After i add on local computer 10.200.1.30 route like:
route add 10.200.40.0 255.255.255.0 10.200.40.3
Everything began to work perfectly, iperf show this(with the same settings):
[ ID] Interval Transfer Bandwidth [ 4] 0.00-1.00 sec 66.5 MBytes 558 Mbits/sec [ 4] 1.00-2.00 sec 68.5 MBytes 574 Mbits/sec [ 4] 2.00-3.00 sec 68.0 MBytes 571 Mbits/sec [ 4] 3.00-4.00 sec 69.6 MBytes 584 Mbits/sec [ 4] 4.00-5.00 sec 46.0 MBytes 386 Mbits/sec [ 4] 5.00-5.24 sec 16.2 MBytes 562 Mbits/sec
And now i'm stucked - how i can push all traffic from 1.0 for 40.0 subnet through remote GW, not for each machine? And vice versa - from 40.0 to 1.0:)
I can't add GW to interface LAN - i get "The gateway address 10.200.40.3 does not lie within one of the chosen interface's subnets.".
Thank you in advance!
How are the two networks connected now? You can't send traffic through a gateway in another subnet like that. You need some kind of transit network. For example, if it's a dedicated circuit, you'd have that plugged into an additional NIC (or VLAN) on both pfSense firewalls, and then you'd have some other unrelated subnet to talk between them there. Then you use the address in that subnet as a gateway to reach the other.
If you have your LANs plugged together so they're all in the same Layer 2/flat network that is going to be a huge mess.
